Abstract: PROBLEM TO BE SOLVED: To manufacture a color filter even in the case of a light shielding layer being narrow by forming an ink layer thinner than the width of a transmission area part and higher than the height, on a printed body, and rolling the ink layer on the printed body. SOLUTION: A recessed plate 1 with a plurality of grooves 2 with a width w1 , narrower than the width w2 of a desired transmission area part and a depth larger than the height of the transmission area part is used, and printing is performed using this recessed plate 1 with the grooves (ink cells) 2 formed narrower in width than the transmission area part, and a base 4 with a light shielding layer 3 formed almost to the same height as the height of a product, that is, the height of the transmission area part. After forming an ink layer on the base 4, the ink layer is rolled, and the spread ink layer is dried and hardened. The desired transmission area part can therefore be positively formed even in the case of the light shielding layer 3 is thin.

Abstract: PURPOSE:To measure the amplitude and phase characteristics, etc., of optical components with high accuracy by comparing the electric output of a 1st filter part with an electric signal relative to the frequency difference between 1st and 2nd light outputs. CONSTITUTION:The 1st light output of a variable frequency light source 1 is incident on the object 10 of measurement through an optical directional coupler 2, etc., and its emitting light is incident on a polarization control part 41.

Title: Chip capacitor
Inventor: KISHIDA KAZUTO
IPC: H01G4/255
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To digitally reduce if capacitance by forming upper electrodes of a capacitor having the structure in which a dielectric thin film is sandwiched by metal thin films in a bamboo blind shape and cutting the electrodes one by one by a laser. SOLUTION: A dielectric thin film 4 is sandwiched in parts where an lower electrode 3 (Cr/Cu/Cr thin film) and upper electrodes 5 (Cr/Cu/Au thin film) formed in a bamboo blind shape are overlapped, thereby forming a capacitor part. Each of the capacitor parts has the same area, the dielectric film 4 has a uniform film thickness, and the net capacitance is equal. By cutting the electrodes 5 one by one by a laser trimmer, the capacitance value is digitally reduced. Consequently, the area occupied by the capacitor parts which can be trimmed is reduced and backlash is prevented, so that mechanical adjustment is unnecessary.

IPC: G02B6/12
Filed: 1987-10-15
Abstract: PURPOSE:To decrease frequency dispersion and to enable modulation up to extra-high frequencies by using a superphotoconductor as an electrode material in order to change the coupling constant between two light guides by an electro- optic effect. CONSTITUTION:The conventional normal conductor is changed to a superconductor and is then used as a microwave strip line 23 which constitutes a part of an optical modulator.

Tc=90K class grows as a single crystal on a perovskite type dielectric substrate (for example, SrTiO3 or LiNbO3), etc.). The microwave strip line 23 formed of the superconductor is the extremely small frequency distribution to frequencies below the gap energy intrinsic to the superconductor and has the excellent capability as the transmission line for extra-high frequencies. For example, the oxide superconductor of the Y-Ba-Cu-O system has 30meV gap energy and is capable of transmitting the extra-high frequencies up to about 10<12>Hz; therefore, the light modulation by the extra-high frequencies in 10<12>Hz order is possible.

Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To attain quick detection of out of synchronism of a random number and re- synchronization by using a D channel so as to send a random number synchronizing signal discrimination signal during enciphered voice communication. SOLUTION: A transmitter side and a receiver side are connected by using a call connection signal K from a D channel control section 6 of a ciphering equipment 1. Then a synchronization processing section 5 in the transmitter side generates a random number synchronization discrimination signal T by using random number information of a random number generation ciphering section 2 at each proper time interval during transmission of a ciphered voice signal Sa through the use of a B channel. Then the signal T is transmitter from the control section 6 to the reception side by using the D channel.  A synchronization processing section 5 in the receiver side generates information of a random number with the same number as a random number designated by the signal T based on information from a random number generation decoding section 3, compares both the random numbers and discriminates it that out of synchronism of random number takes place in the case of inequality. Thus, countermeasures are taken by quickly detecting random number out of synchronism and accurate transmission of information is attained.

Abstract: PROBLEM TO BE SOLVED: To prevent a splashed developer from being stuck to the bottom part of a developer housing part by providing the developer housing part with a sheet-like low resistance part which is hard to be electrified by low resistance at the bottom part opposed to a holding means for detachably holding another developing unit. SOLUTION: A toner housing part 21BG is provided with a bottom part opposed to a holding means for detachably holding another developing unit. Then, a low-resistance cover sheet 21BR being a low resistance member is stuck to the bottom surface of the bottom part. The sheet 21BR is constituted of a super high molecular polyethylene sheet material whose surface resistance is <=106 Ω. Since the resistance of the sheet 21BR is low, the surface thereof is not remarkably electrified. Besides, since the sheet 21BR is constituted of the sheet material such as the super high molecular polyethylene sheet material whose friction coefficient is low, the surface thereof is excellent in slidability. By these two characteristics, color toner suspending in a printer main body can be prevented from being stuck.
